Problems solved by technology

However, with an increase in the number of nozzles and a high density of nozzles, the number of terminals increases, and if the terminal pitch is narrowed, it is difficult to perform the pitch conversion without changing an interval between one terminal and the other terminal.
In other words, as a wiring is positioned closer to the outside, among arranged wirings, the wiring has a steeper inclination relative to the arrang

Abstract

An electronic device includes a sealing plate including a first surface connected to a pressure chamber formation substrate, and a second surface having a drive IC provided thereon. The sealing plate includes a first region in which a plurality of individual connection terminals are arranged, and a second region in a position different from the first region. A plurality of bump electrodes are arranged at a pitch different from a pitch of an individual connection terminals, in a region overlapping a second region, and a wiring group connecting the individual connection terminal and a bump electrode includes a first wiring of which a position of a pass-through wiring relaying the first surface and the second surface is within the first region. A second wiring of which a position of a pass-through wiring connecting the first surface and the second surface is within the second region.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to an electronic device provided with a wiring substrate having wirings formed thereon.[0003]2. Related Art[0004]An electronic device includes a drive element such as a piezoelectric element to be deformed in response to an applied voltage, and the electronic device is applied to various types of devices, sensors, or the like. For example, a liquid ejecting apparatus ejects various types of liquid from a liquid ejecting head using the electronic device. Examples of the liquid ejecting apparatus include an image recording apparatus such as an ink jet printer and an ink jet plotter, but in recent years, the liquid ejecting apparatus has also been applied to various manufacturing apparatuses, by taking advantage of features that a very small amount of liquid can be accurately landed at a predetermined position. For example, the liquid ejecting apparatus has been applied to a display manufacturing apparatus that manuf...
